Title: Improvements in or relating to the manufacture of projectiles
IPC: B21K1/02
Filed: 1942-02-24
Abstract: 575,388. Making projectiles. ARON, H., and JOSEPH, A. Feb. 24, 1942, No. 2445. [Classes 83 (ii), 83 (iii) and 83 (iv)] Milling; breaking; forging; extruding.-In a process of, and apparatus for, forging projectiles, the billet is first electrically heated while gripped by pairs of electrodes 13, 15, and drawn out to form two pointed blanks 19, 20, Fig. 2, which are then forged and mounted while still hot so that they are revolved about a fixed axis and shaped by a rotary grinding or milling tool. The pointed blank shown in Fig. 2 is transferred to a support 32, Fig. 3, where it is gripped between half dies 30, 31 carried respectively by a fixed member 27 and a movable member 28 which is withdrawn against springs 40 to allow insertion of the blank by means of a lever 41. The blank is then shaped by lowering the upper die 37 which is mounted in a holder 36 and has a central aperture 38 so that when the upper die is lowered the point of the blank is shaped and the weak metal at the point of the forging is extruded through the aperture 38 in the form of a plug 44. The blank, still at forging heat, is then placed point downwards in a holder 50, Fig. 4, where the plug 44 is sheared off by a cutting-blade 55 coacting with a hardened plate 52. The blade is mounted in a crosshead 54 actuated by a hydraulic ram 56. The still hot blank is then placed on a pair of knurled rollers 83, 84, Fig. 6, of a milling- machine where the point is milled by a cutter 62 arranged on an axis transverse to the blank axis and having rasp-like hardened teeth 66 forming a surface, complementary to the desired shape of the projectile nose. The rollers 83, 84 are driven from a motor by gearing 87 and are mounted on a carriage 68 which may be reciprocated to move the work to and from the cutter by means of rack teeth and a quadrant operated by a lever 72. The limits of movement are determined by adjustable stops on the hub of the quadrant coacting with a fixed projection. A spring-urged lever arm 92 carries rollers 94, 95 which force the work downwards so that it is rotated by the rollers 83, 84. When the work is moved back after the operation, a cam prises the arm 92 against a spring so .that the work may be removed. A bearing 98 supports the work against end thrust. Instead of forging the work by the die 37, the work-pieces may be forged between split drop forging-dies and the longitudinal flash cut off before finishing the point by the tool 62. Specifications 465,103, 549,569 and 574,931 are referred to.

Patent GB-735513-A (GB)
Title: Improvements in or relating to the protection of silver and like surfaces
IPC: C23C14/08
Filed: 1952-02-01
Abstract: The surfaces of articles of tableware or table cutlery made of silver or silver alloys are protected against tarnishing and corrosion by applying a dense, pore-free and permanent layer, measuring 50 to 500 A in thickness, of one or more non-light-absorbent oxygen compounds of silicon or metals of the second to fifth groups of the periodic system which are resistant to water, heat and atmospheric chemicals. Compounds specified are the oxides of aluminium beryllium, magnesium, titanium, zirconium, thorium, germanium, tin, niobium and tantalum; rare-earth oxides; silicon dioxide and monoxide; twin oxides such as thorium-titanium oxide or compounds of spinel-like character, such as aluminium-beryllium spinel; compounds of silicon dioxide with other oxides, such as silicates of aluminium and zirconium; and compounds of silicon monoxide with other oxides, e.g. zirconium and titanium oxides.  Mixtures, or successive layers, of different oxides may be applied.  The oxide layer may be applied by evaporating the oxides in a vacuum, from sources of evaporation facing the silver surface to be protected, the sources being heated electrically by induction or resistance heating, or by cathode sputtering in a residual atmosphere of an inert gas, e.g. argon, or of carbon monoxide, at a pressure of 10-2 to 10-3 mm. of mercury, the cathodes being previously provided with a coating of the oxide to be applied to the silver.  Such methods as the vapour-deposition of layers of the oxide or of anodic oxidation, or e.g. precipitation of zirconium oxide on a heated tungsten sheet from a mixture of zirconium chloride, carbon dioxide and hydrogen, may be used for coating the cathode.  The articles to be coated may be placed on charge plates which are connected as anodes in the sputtering apparatus, and are preferably cooled, e.g. by circulation of water.  The apparatus may comprise a number of such charge plates, arranged in tiers, with the cathodes above them. Coatings consisting of mixed oxides or of laminations of different oxides, may be obtained by using a cathode subdivided into relatively insulated strips carrying layers of different oxides, preferably with control means permitting them to be maintained under current alternately, in rotation, or simultaneously.  Specifications 595,287, [Group III], 632,422, [Group XL (c)], and 650,173 are referred to.

Abstract: 1358942 Supply circuits for brushless motors FORD MOTOR CO Ltd 20 Jan 1972 [8 March 1971] 2806/72 Headings H2J J14A J14B J14D J14X J12N1 J12N3Y J12N3A J12N3B J12NX J12C J12H2 J1H1 and J1J [Also in Division H3] In a combination of a reluctance motor and a control circuit, after current has been passed through one portion of a winding of the motor from a D.C. source, the circuit may be caused to permit the magnetic energy stored in the winding to set up a circulating current in a closed loop including the above portion of the winding and an additional portion. In the combination shown, a portion 76' of one phase winding 76 of a polyphase reluctance motor of the type shown in Fig. 1 of Specification 1240979 is energized from a battery 80 on triggering a thyristor 86. A thyristor 114 may later be triggered to permit a positive voltage on plate 118 of a capacitor 108 to reverse bias and switch off thyristor 86, the capacitor then discharging through winding portion 76'. While the discharge current is flowing, thyristor 92 is triggered to allow current to freewheel round the winding. The motor is of the type controlled in dependence on rotor position and at the end of the conduction period of phase winding 76 (when the associated stator and rotor poles are in alignment) the energy stored in the winding is returned to the battery through rectifier 94. The rectifier 94 and thyristor 92 may be connected to the winding at some point between the mid-point 77 and the lower end, as viewed in Fig. 1, of the winding, Fig. 2 (not shown), and the thyristor 86 may be connected between the points 90 and 104, Fig. 3 (not shown). The circuit to the right of terminals 102, 104 and serving to switch off thyristor 86 may be replaced by various other circuits, Figs. 3 to 8 (not shown) all of which include a capacitor, the voltage on which is used to reverse bias thyristor 86 (see Division H3). Different operating modes of the control circuit for high and low motor speeds are disclosed. The thyristors may be replaced by transistors or triacs.
